Item 20- Discuss Water Supply Concepts, Including Reclamation

1
Item 20- Discuss Water Supply Concepts,
Including Reclamation

• MPWMD Board Meeting
• March 15, 2004
• Staff Contact Henrietta Stern

2
Water Sources Reviewed

• Pebble Beach Wastewater Reclamation Project --
  benefited properties
• PB Reclamation -- MPWMD share
• Paralta well community drought reserve
• Conservation savings
• Aquifer storage and recovery (ASR)
• Seaside Basin in-lieu recharge.

3
Important Reminders

• All Cal-Am water comes from Carmel River Basin or
  Seaside Coastal Subareas there are no other
  sources at this time.
• SWRCB Order 95-10 controls use of Carmel River
  (11,285 AFA diversion limit one-for-one
  replacement)
• Seaside Basin hydrologic trends and ongoing
  litigation potentially limit use.

4
Pebble Beach Reclam. Project Benefited Properties

• SWRCB recognizes up to 380 AF that can be added
  to 11,285 AFA diversion limit
• Water goes only to benefited properties, and only
  in Del Monte Forest
• Ordinance No. 109 in progress to help fund Phase
  II project expansion/improvements to maximize
  reclaimed water production and minimize need for
  Cal-Am water.

5
Pebble Beach Reclam. Project MPWMD Share

• Up to 420 AF to MPWMD (not recognized by SWRCB to
  add to 11,285 AF limit)
• Assumes 800 AFA Cal-Am production is replaced
  280 AFA shortfall estimated
• No more than 140 AFA should be released (420
  280 140) this would be Carmel River water
• Need CEQA review, based on Ordinance No. 84
  litigation.

6
Paralta Well Community Drought Reserve

• No physical reserve from Paralta Well ever
  existed 1,000 AFA used from beginning
• Physical limits to Cal-Am system prevent greater
  use of Paralta well
• Seaside Basin issues stymie use
• Formal MPWMD policy against allocation of 385 AF
  reserve is presently in effect.

7
Conservation Savings

• MPWMD conservation program since 1987
• 2,040 AF estimated as permanently saved 20
  savings despite 16 increase in customers
• Conservation enables compliance with Order 95-10
  limits
• Conservation is affected by weather, emotions
• How much more savings without hardship?
• Recommend not using conservation savings.

8
Future Water Source -- ASR

• Aquifer storage and recovery is promising
• 941 AF injected and 440 AF recovered to date
• Aquifer recharge and water quality benefits
• Up to 1,300 AF with minor improvements to Cal-Am
  system larger sizes too expensive
• Need many permits for long-term program MPWMD in
  progress with water rights.
• Worthwhile to pursue, even with Order 95-10.

9
Future Source Seaside Basin In-Lieu Recharge

• MPWMD asked SWRCB to approve using more Carmel
  River water in wet years to let Seaside rest
  and recharge Seaside could safely produce in dry
  years with less impact to river.
• SWRCB staff rejected MPWMD request for temporary
  relief in letter dated January 14, 2004
  (distributed at January 29, 2004 meeting).
• MPWMD continues to pursue concept through
  long-term Petition for Change.

10
Summary of Concepts

1. Stop bottom up planning based on uncertain
   water sources recognize existing top down
   limits (15,285 AFA) (Note 14,785 AFA production
   is less risky.)
2. Recognize misconceptions about many water
   sources. All Cal-Am supply comes from Carmel
   River Basin and Seaside Basin Coastal Subareas.

11
Discussion Concepts, continued

• 3. Prepare an EIR on Water Allocation Program
  based on existing limits and recent trends EIR
  must define and evaluate proposed project and
  alternatives.
• 4. Importantly, the SWRCB can change the 11,285
  AFA limit. It is not a water right.

12
Basic EIR Questions

• How much water is available to allocate? Relates
  to risk of exceeding SWRCB 11,285 AFA Carmel
  River limit and protecting Seaside Basin.
• Who gets how much water? Distribution of water to
  jurisdictions affects cumulative growth impacts
  (e.g., traffic, air quality, biology).
• How to handle 156 AF existing tabulated
  jurisdiction allocations? Affects how much water,
  if any, is available for new uses.

13
Specific EIR Questions

1. How much water is used from Carmel River and
   Seaside Coastal Subareas now?
2. Compare actual use to SWRCB limit on Carmel River
   and Seaside production goals.
3. Assess wiggle room how much to allocate and
   not go over 11,285 AF Carmel River limit?
4. Policy trade-off of economic benefits versus risk
   of more rationing, Seaside Basin impacts, or
   exceeding SWRCB limit (large fines).

14
EIR Questions, continued

• 5. Should military and District community reserve
  be added as jurisdictions?
• 6. Should all or some of the existing 156 AF on
  MPWMD books be preserved? Under what conditions?
  
• 7. Who pays for EIR funding issues. Joint
  funding a possibility?

Specific Allocation Concepts

• Higher the allocation, the higher the risk of
  exceeding 11,285 AFA limit.
• 560 AF is higher risk maximum based on
  1998-2003 Carmel River production average.
• 260 AF is intermediate risk maximum based on
  1997-2003 Carmel River production average.
• 100 AF is lower risk maximum based on closest
  Carmel River production to SWRCB limit, except
  1997.
• Zero allocation is safest (still some risk).

17
Preserve 156 AF for Jurisdictions or Not?
   
 
18
Allocation Sources

• Actual drinking water comes from Carmel River
  (subject to SWRCB restrictions) and Seaside
  Coastal Subareas.
• Sources such as 140 AF from MPWMD share of
  Pebble Beach Reclamation Project is not a
  separate supply source, and is not recognized by
  SWRCB.

19
Overview of January 28, 2004 TAC/PAC Meeting

• The concept of 140 AF allocation was suggested by
  Chairman Edwards.
• Did not specify whether this would be in addition
  to or instead of the 156 AF currently tabulated
  for jurisdictions.
• TAC/PAC did not have a recommendation on
  allocation issues at the meeting.

20
Recommended Board Action

• Discuss concepts and provide direction on key
  questions.
• At this time, consider providing direction on
  process and committee/community involvement in
  developing proposals and alternatives for an EIR.
